APPARATUS FOR DYEING UNDER PRESSURE.

SPECIFICATION forming part of Letters Patent No. 773,378, dated October25, 1904.

Application filed February 10, 1904:. Serial No. 193,013.

1'0 (all w/wm, it warty concern:

Be it known that I, LEON DETRIt, dyer, a citizen of the French Republic,residing at Reims, Department of Marne, France, have invented certainnew and usefulImprovements in Apparatus for Dyeing Yarns, of which thefollowing is a specification.

This invention relates to an apparatus for dyeing under pressure yarnswound up ,in the form of bobbins, and has for its object to dyeregularly without great expenses of manual labor and with a greatrapidity the yarns with the most delicate shades.

Inthe annexed drawings, Figure 1 is an elevation of the disposition forcarrying out the new process. Fig. 2 is a plan view, and Fig. 3 a detailof the same. 7

In the casing a of an apparatus for dyeing under pressure one or manysupports 6 are disposed. The support I) is a hollow triangular prism thebases of which are closed, one of these bases being provided with anozzle 0, which is fitted to an apparatus which insures the circulationof the dye. On the faces of the prism are fixed hollow cylinders (Z,having internally the size of a bobbin of the yarn to be dyed. The facesof the prism are perforated with many holes in the parts correspondingto the bottom of the hollow cylinders (Z. The other end of these hollowcylinders are opened or closed by a perforated lid or by other suitablemeans allowing the dye to pass. 7

For dyeing the yarn and for the preparatory or subsequenttreatmentcleaning, mordanting, washing, &c.the bobbins are introducedeach in a casing (Z, and the support 6 is brought into the casing a ofan apparatus for dyeing under pressure. According to the triangularshape of the supports 5, these supports may be disposed forfillingnearly completely the casing a. The circulation of the liquor is set upas usually. The dye is forced under pressure alternatively from theinner part of the prism through the bobbins in the casinga and from thecasing a in the prism Z). The circulation of the liquid can also takeplace only in one of these directions. In order to oblige the dye topass equally in all parts of the bobbin,-

although the yarn is more pressed in the central (No model.)

part than in the periphery, the wooden spindle on which the yarn hasbeen wound up is supplied with a tube 6, which is perforated in itscentral part, Fig. 3, and provided in its inner part with a water-tightpartition f, which is disposed in the middle if the circulation of thedye takes place in the two directions and at the end of the perforatedpart if the circulation takes place only in one direction. Thispartition prevents the dye from passing through the tube and forces itto pass through the central part of the bobbin and to pass through thebobbin perpendicularly to its axis with the same activity as the currentpassing in a parallel-direction with the axis. The central part willthus be sufficiently dyed.

Having thus described my invention and in what manner the same may beperformed, I

declare that what I claim is- 1. An apparatus for dyeinginvolvingahollow support closed at its top and having its bottom formedwith a passage, said support having each of its sides provided with aplurality of separate groups of perforations, a plurality of hollowcylinders fixed to each side of said separate support and surroundingsaid groups of perforations in each side, a hollow perforatedbobbin-spindle arranged in each of said cylinders and provided with animperforate partition arranged intermediate its ends, a perforatedclosure for the outer end of each of said cylinders, and a suitablecasing inclosing said support and cylinders.

2. A dyeing apparatus involving a hollow support closed at its top andhaving its bottom formed with a passage, said support having each of itssides provided with a group of perforations, a separate hollow cylindersecured to each of the sides of said support and surrounding the groupof perforations in each side, a removable hollow perforatedbobbinspindle arranged in eachof said cylinders and providedintermediate its ends with an imperforate partition, a perforatedclosure for the outer end of each of said cylinders, and a suitablecasing inclosing said support and, cylinders.

3. A dyeing apparatus involving a hollow bobbin-spindle perforated aportion of its length intermediate its ends and further provided with animperforate partition arranged intermediate of said perforated portion.

4.. An apparatus for dyeing involving a hollow triangular-shaped supportclosed at its top and having its bottom formed with a passage, saidsupport having each of its sides pro vided with a plurality of separategroups of perforations, a plurality of hollow cylinders fixed to eachside of said support and surrounding said separate groups ofperforations in each side, a hollow perforated bobbin-spindle arrangedin each of said cylinders and provided with an imperforate partitionarranged intermediate its ends, a perforated closure for the outer endof each of said cylinders, and a suitable casing inclosing said supportand cylinders.

5. A dyeing apparatus involving a hollow triangular-shaped supportclosed at its top and having its bottom formed with a passage, saidsupport having each of its sides provided with a group of perforations,a hollow cylinder secured to each of the sides of the support andsurroundingsaid group of perforations in each side, a hollow perforatedbobbin-spindle arranged in each of said cylinders and providedintermediate its ends with an imperforate partition, a perforatedclosure for the outer end of each of said cylinders, and a suitablecasing iuclosing said support and cylinders.

6. An apparatus for dyeing, comprising a casing having inlets andoutlets in the side thereof and further provided with a passage at oneend thereof, a vertically-extending hollow triangular-shaped supportsecured within said casing, closed at its top and having its bottomformed with a passage communicating with the passage of the casing, saidsupport having each of its sides provided with a plurality of separategroups of perforations, a plurality of hollow cylinders secured to eachside of said support and surrounding the separate groups of perforationsin each side, a hollow perforated bobbin -spindle arranged in each ofsaid cylinders and having secured therein intermediate its ends animperforate partition, and a perforated closure-plate for the outer endof each of said cylinders.

7. An apparatus for dyeing involving a hollow support having each of itssides provided with separate groups of perforations, bobbininclosingcylinders secured to each of the sides of the support and surroundingthe separate groups of perforations, said perforated portions of thesides of said support constituting one end of said cylinders, aperforated closureplate for said cylinders, and a bobbin-spindlearranged in each of said cylinders and having a portion of its lengthintermediate its ends perforated and further provided with animperforate patrition arranged intermediate said. perforated portion.

8. An apparatus for dyeing involvinga triangular-shaped hollow supporthaving each of its sides provided with separate groups of perforations,bobbin-incl'osing cylinders secured to each of the sides of the supportand surrounding the separate groups of perforations, said perforatedportions of the sides of said supportconstituting one end of saidcylinders, a perforated closure-plate for said cylinders, and abobbin-spindle arranged in each of said cylinders and having a portionof its length intermediate its ends perforated and further provided withan imperforate partition arranged intermediate said perforated portion.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
